So maybe what we need is a way to designate a process as "untrustable". An
untrustable process would never be allowed to create devices, change its id
to root (though it could start as root and change to someone else), load
LKMs, set a setuid bit, <add your insecure list here>. Any children it
created would also be untrustable. This would be ideal for running most
daemons. And it would be a totally separate mechanism than chroot; some
programs would use one mechanism, some both, and some none.
